LPC2388 Ethernet: Command-Line "Connection failed: comms error"

[thomas]

Hi everybody,

I am trying to program the LPC2388 by using the build-in command line functions. However this is not working properly.

Flash Magic Version 7.50.3174
8051/XA Driver Version 3.03.3043
ARM UART Driver Version 3.04.3043
ARM Cortex UART Driver Version 4.56.3174
ARM Ethernet Driver Version 2.04.3043
ARM Cortex Ethernet Driver Version 2.06.3043
ARM CAN Driver Version 2.07.3134

VERIFY(C:\Users\rth3fe\Desktop\ELU_V186_C1_ETH_iptest.hex, NOCHECKSUMS)


The command file was directly saved from option "File > Save Command Line Directives" after a successful programming of the device through the gui.



Please give me some advice on how to handle this.

Thanks!

Please double-check that the settings in the command line match exactly the settings in the GUI and nothing is missing.

Check the output from Flash Magic using Wireshark to compare the GUI with the command line and let us know what the difference is.

Hi Andy,

my computer uses two Ethernet Cards. There is a "Interface" option on GUI but it seems there is no equivalent option for the command line tool. The rest of the settings are matching to the GUI's.
I analyzed the communication using Wireshark, too. There are broadcasts (3 to be exact) to the LPC2388. After the third broadcast, the tool exits with said error.

Connection failed: comms error

Edit:
Some specs of my system may help:
OS: Windows 7 Pro
Network card: Realtek RTL8169/8110 Family PCI Gigabit Ethernet

The command line will use the first Ethernet interface found - choosing an interface is currently not supported, mostly due to them having painfully long names.

You need to compare the wireshark output from the GUI working with the command line not working to see what the difference is.
